Translation of nudismo

Hi, I'm back from my vacation. It gives me pleasure to learn Spanish, because I can feel the improvement continously. I studied medicine in the University of Montpellier, a student city in France.
My mother tongue is Spanish. For one year I lived in Spain. I'm from Huston, Texas, USA, originally. I want to study Spanish literature next year. I have already been to my professor to discuss it.
I am back in Switzerland, and the weather makes me crazy. Shall I write you on Vocabulix or to your regular email address? I have been working 20 years as an employee for a German company.
